The land slopes west ward from central India due to deposition of alluvial fan. The rift valley which is occupied by the Narmada is one of the reasons of Narmada flowing to the west. The rift is formed due to complex natural processes leading to either subsidence or upliftment of the earth’s surface. The area is seismically active and has seen major upheavals. Such movements reshape the landscape. There is readjustment of slopes and rivers either start bringing more material or change course.
